Title: Digital visual and sensor simulation system for generating realistic scenes
Inventor: NACK MYRON L
IPC: G06T15/06
Filed: 1987-08-11
Granted: 1991-03-26
Abstract: DIGITAL VISUAL AND SENSOR SIMULATION SYSTEM     FOR GENERATING REALISTIC SCENES     ABSTRACT OF THE DISCLOSURE    A system using a ray-tracing algorithm and a hierarchy of volume elements (called voxels) to process only the visible surfaces in a field of view.  In this arrangement, a dense, three-dimensional voxel data base is developed from the objects, their shadows and other features recorded, for example, in two-dimensional aerial photography.  The rays are grouped into subimages and the subimages are executed as parallel tasks on a multiple instruction stream and multiple data stream computer (MIMD).  The use of a three-dimensional voxel data base formed by combining three-dimensional digital terrain elevation data with two-dimensional plan view and oblique view aerial photography permits the development of a realistic and cost-effective data base.          Hidden surfaces are not processed.  By processing only visible surfaces, displays can now be produced depicting the nap-of-the-earth as seen in low flight of aircraft or as viewed from ground vehicles.  The approach employed here is a highly-parallel data processing system solution to the nap-of-the-earth flight simulation through a high level of detail data base.          The components of the system are the display algorithm and data structure, the software which implements the algorithm and data structure and creates the data base, and the hardware which executes the software.  The algorithm processes only visible surfaces so that the occulting overload management problem is eliminated at the design level.  The algorithm decomposes the image into subimages and processes the subimages independently.

Abstract: C381.1/M                       ABSTRACT        Title:  Microwave Ovens and Methods of Cooking Food A microwave oven has a magnetron for delivering microwave power to the oven cavity, and a fan (36) and electrical resistance heating element (38) for recirculating hot air through the cavity.  The oven cooks cakes by subjecting the cakes to a first cooking stage during which hot air but no microwave power is produced, and a second cooking stage during which microwave power is produced but the electrical resistance heating element (38) is not energised, and a third cooking stage during which hot air power is applied and microwave power is produced for a certain proportion of the third cooking stage.  The transitions between the stages are determined by the recirculated air temperature as detected by a thermocouple (40) positioned to detect the temperature of the air as the latter leaves the oven cavity.

Title: Pasteurizable, freeze-driable hemoglobin-based blood substitute
Inventor: HSIA JEN-CHANG
IPC: A61K38/16
Filed: 1988-04-29
Granted: 1992-08-18
Abstract: ABSTRACT OF THE DISCLOSURE           The present specification describes a process by which a blood substitute (hereinafter referred to as "HemoSafe") is derived from uniformly stabilized monomers and polymers of deoxyhemoglobin in its tight (T) conformation, with oxygen affinity similar to that of human blood.  Two classes of HemoSafe are derived respectively from animal-hemoglobin and human-hemoglobin.  HemoSafe (animal) differs from HemoSafe (human) in that it is free of polymers in order to reduce potential immunogenicity if used in man.  Both types of HemoSafe may be derived in the following manner.  The stabilized deoxyhemoglobins are converted to their carbonmonoxy derivatives (CO-HemoSafe) which are then stable under pasteurization conditions to render them viral disease transmission-free.  CO-HemoSafes are stable for 2 months at 56°C in either the solution or the freeze-dried state.  For transfusion CO-HemoSafes are easily oxygenated under sterile conditions by photoconversion yielding oxy-HemoSafe.  In addition a transfusable met-hemoglobin derivative for treatment of cyanide poisoning, is derived by converting oxy-HemoSafe to met-HemoSafe.

Abstract: ABSTRACT OF THE DISCLOSURE            This  invention  provides  an  improved  set  of extrusions whereby a window can be assembled on-site from lengths of extrusion, rather than pre-made in a work shop.  By the use of at least two extrusions, one of which is directly attached to the  window aperture,  for  each of the  sill, jambs,  and head piece,  irregularities in and warping  of  the  window  framed  aperture  are accommodated by inserting shims either between these extrusions, or between the extrusions and the window aperture.  The shims are channel-like extrusions, which, on assembly, are adjusted to the required thickness by cutting the side walls of the channel.  After the window is assembled into the aperture, any shims used are hidden by the extrusions.

Abstract: "Interface Module for Connecting Collision Detection LAN User Terminals to Different Access Mode Switching Network"               ABSTRACT OF THE DISCLOSURE In an interface module for connecting user terminals of the carrier sense multiple access collision detection (CSMA/CD) local area network (LAN) to a different access mode switching network, a transmit buffer is connected at one end through a transmit data channel to a user terminal and connected at the other end to a desired switching system. A receive buffer is connected at one end to the switching system to store a receive packet supplied from it. An OR gate is provided having a first input connected to the transmit data channel, a second input connected to the other end of the receive buffer and an output connected through a receive data channel to the user terminal. A detector circuit detects when a transmit packet is received from the user terminal. A control circuit responds to the output of detector circuit to enable the transmit buffer to store the transmit packet from the user terminal and further enables the receive buffer to forward the stored receive packet to the OR gate in the absence of a transmit packet detected by the detector circuit. The control circuit detects a simultaneous occurrence of a receive packet being forwarded from the receive buffer and a transmit packet being detected by the detector means and causes a collision-presence signal to be supplied to the user terminal through a signalling channel.
